## Summary
This is a small correctness improvement that ensures that we avoid using
stale cache entries for local dependencies in the install plan. We
already have some logic like this in the source distribution builder,
but it didn't apply in the install plan, and so we'd end up using stale
wheels.
Specifically, now, if you create a new local wheel, and run `pip sync`,
we'll mark the cache entries as stale and make sure we unzip it and
install it. (If the wheel is _already_ installed, we won't reinstall it
though, which will be a separate change. This is just about reading from
the cache, not the environment.)
Add directory `--find-links` support for local paths to pip-compile.
It seems that pip joins all sources and then picks the best package. We
explicitly give find links packages precedence if the same exists on an
index and locally by prefilling the `VersionMap`, otherwise they are
added as another index and the existing rules of precedence apply.
Internally, the feature is called _flat index_, which is more meaningful
than _find links_: We're not looking for links, we're picking up local
directories, and (TBD) support another index format that's just a flat
list of files instead of a nested index.
`RegistryBuiltDist` and `RegistrySourceDist` now use `WheelFilename` and
`SourceDistFilename` respectively. The `File` inside `RegistryBuiltDist`
and `RegistrySourceDist` gained the ability to represent both a url and
a path so that `--find-links` with a url and with a path works the same,
both being locked as `<package_name>@<version>` instead of
`<package_name> @ <url>`. (This is more of a detail, this PR in general
still work if we strip that and have directory find links represented as
`<package_name> @ file:///path/to/file.ext`)
`PrioritizedDistribution` and `FlatIndex` have been moved to locations
where we can use them in the upstack PR.
I added a `scripts/wheels` directory with stripped down wheels to use
for testing.
We're lacking tests for correct tag priority precedence with flat
indexes, i only confirmed this manually since it is not covered in the
pip-compile or pip-sync output.
Closes#876
## Summary
This PR makes the `pypi_types::File` a response-only type (i.e., a type
that's only used when deserializing over the wire), and adds a separate
internal `File` type. Right now, the representations are similar, but
already, we can avoid the "lenient" deserialization on our internal
`File` type, and avoid the special-casing of the property names that's
required in the JSON. Over time, we can evolve this representation
entirely separately from the representation we receive from PyPI and
other indexes.
From manual inspection, this dataset generated through the [libraries.io
API](https://libraries.io/api#project-search) seems more mainstream than
the current 8k one, which is also preserved. I've added the dataset to
the repo because the API requires an API key.
## Summary
This PR enables `puffin clean` to accept package names as command line
arguments, and selectively purge entries from the cache tied to the
given package.
Relate to #572.
## Test Plan
Modified all the caching tests to run an additional step to (1) purge
the cache, and (2) re-install the package.
This PR adds caching support for built wheels in the installer.
Specifically, the `RegistryWheelIndex` now indexes both downloaded and
built wheels (from registries), and we have a new `BuiltWheelIndex` that
takes a subdirectory and returns the "best-matching" compatible wheel.
Closes#570.
